Air pollution in China has gotten so bad lately that one environmentalist's wacky idea for a solution doesn't seem all that far-fetched: putting clean air in a can.

Last week, when a thick gray haze blanketed Beijing and several other Chinese cities, sending kids to the hospital, grounding planes and causing the government to order cars off the road, Chen Guangbiao took to the streets in Beijing to hand out yellow and green cans of smog-free, non-carcinogenic air.

Ego aside (the bright cans feature an image of Chen's face and the words "Chen Guangbiao is a good man" on them), the clever political stunt is just the sort of thing that China needs these days. Such creative and public protests should help push forward much-needed national reforms to combat air pollution in the country.

A "Clean Air Act" for China is long overdue.

And the recent "air-pocalypse," as the suffocating air pollution that hung over several Chinese cities in January has been termed, should be more than enough proof of that.

"The air has this kind of greenish-gray pallor to it. And it smells like you're standing next to a chemical plant, really chlorine-y," said David Pettit, a senior attorney at the Natural Resources Defense Council, an environmental group. "It's an awesomely bad smell."

Fixing China's air pollution is not just about the country's image or economy, although those certainly suffer because of smog, too. It's about the right of all humans to walk outside and breathe in air that won't choke them or make them sick.

After the city's car culture created a smog problem, scientists started researching protective helmets to protect people. Others wore gas masks. But, eventually the government took action to reduce the pollution. California led the way for the nation, and in 1963, the United States passed the Clean Air Act.

Maybe that's just one man's social media feed. But there's a history of this kind of thing working in China. In 2011, Pan successfully used his online network to press Beijing authorities to report more smog data, according to the Wall Street Journal's China blog.

It's clear the government has taken notice this time as well. Beijing implemented several emergency measures to curb smog. State media is talking about the pollution.

After speaking with a few experts, it seems clear what needs to be done: China has to reduce its reliance on coal, increase renewable energy, regulate the amount of smog-causing sulfur that can go into its diesel fuel and increase vehicle efficiency.

Fixes may be expensive, but the United States has made the compelling case that the costs of enforcing clean air regulations are offset by gains in health and worker productivity. China, which does have some air quality regulations, already seems to be realizing this. The country on Wednesday announced stricter fuel standards that go into effect by the end of 2014 for diesel and 2017 for gas, according to the Financial Times. An environmental official, Wu Xiaoqing, also told state media this week that "China will formulate regulations, standards and policies to reduce air pollutants and control coal burning."

The energy industry estimates it will costs billions for China to meet tougher fuel standards. It may be up to people like artist Ai Weiwei, who posed in a photo wearing a gas mask, and Chen, the man who's peddling cans of clean air, to ensure that the public and the government see that clean air is worth the cost.

"I want to tell mayors, county chiefs and heads of big companies: Don't just chase GDP growth, don't chase the biggest profits at the expense of our children and grandchildren, and at the cost of sacrificing our ecological environment," Chen told Reuters.

If Chinese leaders don't want to drink air from a can, they should listen.
